# facecutter-1: Face cutter : a model beautifier
# The facecutter is a model beautifier : it automatically improves your model by increasing
# the number of faces.
# On smooth_lit faces, the facecutter performs interpolation, so as the faces really look
# smooth (as in this tuto).
# See soya.facecutter.cut.__doc__ for more info.
# Import the Soya module.
import sys, os, os.path, soya, soya.facecutter
soya.init()
soya.path.append(os.path.join(os.path.dirname(sys.argv[0]), "data"))
# Creates a scene.
scene = soya.World()
# Loads the sword model twice
# (we use 'load' instead of 'get' since get would have returned the same object :
# we want 2 DIFFERENT swords, since we are going to modify one of them)
sword1 = soya.World.load("sword")
sword2 = soya.World.load("sword")
# Cuts at least 80 triangles / quads of the second sword.
# Cut triangles / quads are replaced by two triangles, so this mean the sword will have at
# least 80 additionnal faces.
# You can also call the cut fonction by giving the maximum length of the face's edge ;
# every edge longer that the given value will be cut :
# soya.facecutter.cut(sword2, max_length = 1.0)
soya.facecutter.cut(sword2, 80)
# Creates 2 bodys, one for each sword.
body1 = soya.Body(scene, sword1.to_model())
body1.set_xyz(-1.0, -0.5, 0.0)

# in wireframe.

# Creates a light.
